The lower Wabash Valley-215 miles as the river flows from Terre Haute, Ind., to its meeting with the Ohio Valley; 3 to 12 miles across from bedrock wall to bedrock wall; as much as 150 feet from modem alluvial plain to ...

Inventions that greatly benefit mankind are generally not discovered and new industries do not spring up until there is a real need for them. The petroleum industry, which had its beginning in the middle of the 19th century, ...

The limestone building material that has dominated the national market for more than a century is produced in the Bloomington-Bedford district of southern Indiana. Through the years the economy of this two-county area has ...

A part of this data base was originally compiled during research on the Trenton Limestone by Brian D. Keith. Because of increased interest by the petroleum industry in deeper subsurface units in Indiana, we have expanded ...

The problem of sound propagation in an acoustic layer over an acoustic half space (liquid over liquid) is solved by quadrature based on the generalized Filon method. Synthetic seismograms are computed by program NFAR1 for ...

Program HYPOERR evaluates the performance of a small network of arbitrary seismic
arrays in determining coordinates and times of seismic events. A linearized inversion
following the method of Uhrhammer (1980)is performed ...

A program ( FINITEG) uses the finite-element method to deal with problems commonly
encountered in the study of terrestrial heat flow. FINITEG can provide transient and
steady-state solutions to one heat-flow problem or ...

Earth materials in the form of rock and unconsolidated sediments provide a basis for our very existence. They yield building stone, coal, oil, gas, ground water, a wide variety of minerals, and sand and grave, and we grow ...

In very early Pennsylvanian time the place nowcalled Indiana was the locus of subaerial erosion. About 8,000 square miles of this landscape is preserved in western Indiana beneath the rocks of the Pennsylvanian System. ...

Lake Lemon was constructed during 1953 in a hilly, Heavily wooded drainage basin. Considerable lakeside development has taken place after impoundment, and as a result concern has arisen about the sedimentation rate in the ...

An area of 11 counties in southwestern Indiana was studied because ( 1) the subsurface geology of the Salem Limestone and associated rocks in the area contained
numerous correlation discrepancies; (2) it was the locus of ...

Automatic (computer) correlation of geophysical logs is complicated by stratigraphic thickening (or stretch) from one area to another. Previous algorithms compute the stretch with repeated crosscorrelations of the original ...

The scientific paper that is reprinted here is the first published research of a man who
became a leading authority on the geomorphology and stratigraphy of southern Indiana.
During his 35-year career at Indiana University, ...

A part of this data base was originally compiled during research on the Trenton
Limestone by Brian D. Keith. Because of increased interest by the petroleum industry
in deeper subsurface units in Indiana, we have expanded ...

The Indiana coal field forms the eastern edge of the eastern interior coal basin, which is near some manufacturing areas of the United States. For this reason Indiana coal reserves are an important State and National asset.

In 1960 Roland G. Henderson, of the U.S. Geological Survey, published a comprehensive system for computation of first and second derivatives of potential fields
and the continuation of fields to levels above or below the ...
